Dosing system for liquid / self-flowing components

NODOPUR series

Possible applications

  • Series component production
  • Electrical encapsulation
  • Turbine blade production

If the customer specs for the compact MDM Series can no longer be fulfilled, or the desired equipment exceeds the existing capabilities, the NODOPUR Series can be deployed.

The basic model is mounted on a mobile frame with integrated sump tray and is equipped with 40, 60 or 100 l containers. Of course, all other container sizes can also be considered.

The NODOPUR can be manufactured as a 1-component dosing station, but can also be built as a mixing unit with up to 8 components. The system is controlled via a Siemens touch panel on which the PLC programming is visualized. Our internal programming department designs the function and operation of each machine according to customer requirements or optimizes it for the individual process.

In volume flow-controlled systems, the mixing ratio is regulated in the control system in very short cycle times. In systems without volume flow control, the drives also receive their setpoint speeds from the PLC after the system has been calibrated.

Information about possible components and configurations can be obtained from the machine configurator or from our sales team.

    Material Degassing
    • Quality-impairing air and humidity are removed from the resin
    • Improved manufacturing process
    • Enhanced product quality

    Process-integrated evacuation of air and moisture from synthetic resins and hardeners before dosing and mixing with the T-EVAC degassing station.

    With this module you can significantly improve your forming processes as well as your product quality. The new degassing station is suitable for both epoxy resin and polyurethane resin degassing.

    The system solution is designed in two variants: First, as an offline degassing at a central location where several dosing units can be filled with degassed material. Second, as an inline degassing directly integrated into the dosing system and adapted to the process requirements.

    Measurably better results with degassed material

    Material test: Optimal result with degassed resin and hardener

    Test result without degassing: visible air inclusions (light discoloration)

    Heating

    All machine parts, from the container to the hose and mixing head, can be heated to reduce the viscosity of the material – for example, to shorten the pot life or improve mixing of the components. Depending on the application, there are several options available.

    Container

    • Jacket heating (adapted to the container)
    • Double jacket (heating with water or oil)
    • Extra agitators for a better heat distribution

    Hoses

    • Heated hoses
    • Insulation

    Depending on the sensitivity of the material, all possible cold spots must be additionally heated or insulated. Heating cartridges, ring heaters and heating tarpaulins are used in this process.

    Mobility

    It may be necessary for a plant to be mobile, depending on its size and location/purpose. There are several ways to achieve mobility:

    • Mobile frame
    • Own drive unit
    • Trailer coupling

    Volume Flow Control

    Machines with a volume flow control system continuously measure the flow rate of the material and report any deviations to the pumps, which automatically adjust the flow rate accordingly. This happens within seconds and guarantees a constant flow rate and mixing ratio.

    Refill

    To keep the dosing process running longer, we offer refills from IBCs or drums. There are different solutions for the realization of a refill.

    Automatic Refill

    • 1st option: Dosing containers are connected to a mobile refilling station (modern connection with couplings without loss of material)
    • 2nd option: Dosing containers are connected directly on the base frame with e.g. an IBC
    • 3rd option: Refill containers are also located on the base frame

    The process is controlled via automatic refilling e.g. when a minimum sensor level is reached.

    Vacuum Refill

    If the material must not come into contact with air, we offer dosing containers in vacuum atmosphere. When refilling, the negative pressure is used to “pull” the material out of the refill containers.

    Free Refill

    The free refill, also called “free-flow”, uses gravimetry. The material flows from the higher positioned refill container into the dosing containers. No pump is required.
